1.A 2000 W toaster operates on a household circuit of 200 V. What is the resistance of the wire the make up the heating element

MakcuM [25]

P - power measured in watts
E - voltage measured in volts
I - current measured in amperes
R - resistance measured in ohms

$E=IR
\\P=IE$

1. P = 2000 W, E = 200 V, R = ?

$P=IE
\\2000=I200 
\\I=10
\\E=IR
\\200=10R
\\R=20$

2. P = 0.35 W, E = 150 V, R = ?

$P=IE
\\0.35=I150
\\I= \frac{0.35}{150}
\\ E=IR
\\150=\frac{0.35}{150}R
\\R= \frac{150^2}{0.35}
\\R= 64285.71$

Combine like terms to simplify the expression below:<br> 14x - (2x -y) -y STEP BY STEP PLEASE

dimulka [17.4K]

14x - (2x - y) - y
14x + (-1(2x - y)) - y
14x + (-1(2x) - 1(-y)) - y
14x + (-2x + y) - y
14x + 1(-2x + y) - y
14x + 1(-2x) + 1(y) - y
14x - 2x + y - y
14x - 2x
12x

Ronnie is thinking of a number. He says that he gets the same result when he multiplies by his number by 2 as when he adds 5 to

Anettt [7]

Let's say Ronnie is thinking of X.

If 2(x) = x+5, we would first distribute the 2.

2x = x+5

We would then need to isolate the variable. We would do so by getting all variables to one side. The easier choice would be to subtract x from both sides.

2x=x+5
-1x -1x

This becomes

x=5

Ronnie is thinking of the number five.

5•2=10 and 5+5=10.
